"Children who construct the 3D drawings in these books will gain stronger
and stronger skill with the basic tools of Google SketchUp. Each chapter in
these books explains the skills gained in creating the 3D drawing explained in
the chapter. Roskes' creativity flows so strongly that she even wrote an
entire book on how to use Google SketchUp for creating jigsaw puzzles and
various kinds of word puzzles, including a spinning word puzzle. The software
programmers who created SketchUp could never have imagined this unanticipated
use for their software, but Roskes did."
